Merge PDF

    No files selected yet.

    Merge PDF combines several separate PDF files into one single document, in exactly the order you choose. This is useful when you need to send a complete application, join scanned pages, combine chapters of a report, or keep invoices and receipts together instead of attaching many separate files. One tidy document is easier to email, upload, print, and store.

    This tool works entirely in your browser. Your PDF files are processed locally on your device and are never uploaded to a server. That keeps private documents, such as contracts, school records, or financial papers, under your control. It also means merging is usually fast, because you are not waiting for large files to upload and download again.

    How to use

    1. Click the file box and select two or more PDF files from your device.
    2. Check the list that appears. Files will be merged in the order shown.
    3. If the order is wrong, clear your selection and pick the files again in the correct order.
    4. Click the Merge PDFs button and wait while the tool builds your new document.
    5. Save the downloaded file, which is named merged.pdf, when your browser offers it.
    6. Open the merged file once to confirm every page is present and in place.

    Frequently asked questions

    Can I change the order of the files?

    The files are merged in the order you select them and in the order shown in the list. Most phones and computers let you tap files one by one in your preferred sequence. If the list looks wrong, simply select the files again. Checking the list before merging saves time later.

    Why did my merge fail?

    The most common reasons are a damaged file, a file that is not really a PDF, or an encrypted and password protected PDF. Encrypted files often cannot be copied by browser tools. Remove the problem file, unlock it in its original app if you have the password, and then try merging again.

    Will the quality of my pages change?

    No re-encoding is done to your pages. Text, images, and page size are copied as they are into the new document, so the quality should match the original files. The final size will roughly equal the combined size of all the source files.

    Are my documents private?

    Yes. Merging happens locally in your browser, so your documents never leave your device during this process.
